.. _mozilla_projects_nss_reference_fc_setoperationstate: FC_SetOperationState ==================== `Name <#name>`__ ~~~~~~~~~~~~~~~~ .. container:: FC_SetOperationState - restore the cryptographic operation state of a session. `Syntax <#syntax>`__ ~~~~~~~~~~~~~~~~~~~~ .. container:: .. code:: eval CK_RV FC_SetOperationState( CK_SESSION_HANDLE hSession, CK_BYTE_PTR pOperationState, CK_ULONG ulOperationStateLen, CK_OBJECT_HANDLE hEncryptionKey, CK_OBJECT_HANDLE hAuthenticationKey ); `Parameters <#parameters>`__ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~ .. container:: ``hSession`` [in] handle of the open session. ``pOperationState`` [in] pointer to a byte array containing the operation state. ``ulOperationStateLen`` [in] contains the total length (in bytes) of the operation state. ``hEncryptionKey`` [in] handle of the encryption or decryption key to be used in a stored session or zero if no key is needed. ``hAuthenticationKey`` [in] handle of the authentication key to be used in the stored session or zero if none is needed. `Description <#description>`__ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ .. container:: ``FC_SetOperationState`` restores the cryptographic operations state of a session from an array of bytes obtained with ``FC_GetOperationState``. This function only works for digest operations for now. Therefore, a user may call ``FC_SetOperationState`` without logging into the token (to assume the NSS User role). .. _return_value: `Return value <#return_value>`__ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ .. container:: `Examples <#examples>`__ ~~~~~~~~~~~~~~~~~~~~~~~~ .. container:: .. _see_also: `See also <#see_also>`__ ~~~~~~~~~~~~~~~~~~~~~~~~ .. container:: - :ref:`mozilla_projects_nss_reference_fc_getoperationstate`, `NSC_SetOperationState `__
